Cleanup woocommerceUpsell and add upsell links to store

[vraja-pro]

What is the goal of this issue?

In a later issue, property of isWooSeoActive was added to metabox script data. That means woocommerceUpsell can be removed and calculated in the store.

What needs to be done to achieve the goal?

• Go to packages/js/src/redux/selectors/isWooSEO.js and:
  • Add getIsWooActive, and export const getWoocommerceUpsellLink = get( window, "wpseoScriptData.metabox.woocommerceUpsellSchemaLink", "" );
  • Change getIsWooSeoUpsell to be calculated from the properties in the store: getIsProduct, getIsWooSeoActive, getIsWooActive
• Change woocommerceUpsell to use getIsWooSeoUpsell from the store in:
  • packages/js/src/components/SchemaTab.js
  • packages/js/src/containers/SnippetEditor.js
• Change woocommerceUpsellLink to use the store in
  • packages/js/src/components/SchemaTab.js
